Type: article

Abstract: The reactions of (C6F5)3COH with (o -Me2NC6H4CH2)3Dy affords two new Dy3+ tris(alkoxy) complexes isolated in the form of pyridine and NMe3 adducts [(C6F5)3CO]3Dy(L)n (L = py, n = 2 and L = Me3N, n = 1). The first complexes adopts trigonal bipyramidal geometry while the second one is and almost ideal trigonal pyramidal. A characteristic feature of the latter formally four-coordinate complex is the presence of non-covalent intramolecular Dy⋯F interactions with each of (C6F5)3CO- ligands reflected in short contacts, while in the former five-coordinate complex, such interactions were not detected.
